COMBINED SOFA AND FOLDABLE BED Filed Feb. 27, 1952 .2 Sheets-Sheet 2 United States Patent 2,759,198 COMBINED SOFA AND FOLDABLE BED Philip Mednick, Brooklyn, N. Y. Application February 27, 1952, Serial No. 273,628 1 Claim. (Cl. -55) This invention relates to a combined sofa, or chair, and foldable bed in connection therewith, and it has for its object to provide a construction, whereby said sofa may be used independently, and, when desired, may automatically be turned into a folding bed.

Thus, one object of my invention is to provide a foldable bed, which, unlike those now on the market, may be quickly and easily folded and unfolded, and which in the latter position will possess unshakeable rigidity, due to the specific construction hereinafter set forth.

At the same time care has been taken in said construction that the co-related mechanical parts throughout the latter are so positioned that no impediment will ever arise to obstruct the smooth operation of the invention, which latter, whether used as a sofa, or bed, will present a symmetric and stream-lined unit.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangements of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings, forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is an elevational view of my invention.

Figure 2 shows my device in the course of being unfolded.

Figure 3 is a detail side view, showing one of the folding arm in fully collapsed position.

Figure 4 is another detail view.

Figure 5 is a detail view of parts in Figure 1; and

Figure 6 is a detail view of parts in Figure 2.

Referring more particularly to the drawings, the combined sofa and foldable bed comprise a sofa frame having aback portion and arms 21, and a spring unit made up by three frame sections 10, 11 and 12.

Rollers 13, 13 are arranged upon each side at the ends of the rails of the section 12 in order to facilitate the pulling out of the frame sections from the inside of the sofa, or pushing said frame sections back to rest in the space within the sofa, by sliding on the rails 22.

The movement of the rollers 13, 13 is aided by having the latter engage curved angle irons 14, 14 supported by members 22, 22 and 23, 23 of the sofa frame. The members 22, 22 terminate in blocks 24, 24, to provide support and obtain a level surface of the spring unit, when this is in collapsed position.

The forth and back movement of the spring unit is controlled and guided by a special folding unit, shown in Figure 2 and pivotally attached one on each side of section 12, and each comprising a bar 25 to which are pivotally attached the bars 26 and 27, which latter bars, in turn, are pivotally secured to the members 28.

Short arms 29 are rigidly attached to the members 28, and springs 30 connect the bars 25 to the members 28.

The spring unit, when fully pulled out, or extended, is secured in position by the interengagement of the notched section 31 and stud 32 of the respective bars 33 and 34, of which the bar 34 is secured to the front member 52 of the basic structure of the sofa frame.

2,759,198 Patented Aug. 21, 1956 The member 33 forming part of said basic structure is pivotally secured to the section 12 at 55, as shown in Figure 1, and is permitted a limited movement by the slot 55 formed in the member 33 and a pin 75, as shown in Figure 5.

Upon opening and extending the spring sections 10, 11 and 12 one end of the member 35 pushes the member 33 upward at its slotted end, as clearly shown in Figure 1, and thus completes the locking arrangement.

The legs of the center section 11 are actuated by the folding members 35 pivotally connected at one end to the frame section 12 at and pivotally connected at the other end to bars 36 and 37, respectively. The bars 35 are provided with notches 35' for connection to the bars 40 at the pivots 40', when in folded position, as may be clearly seen in Figure 2.

The bars 36 are, as also shown in Figure 2, in turn, pivotally connected to legs 38, while both legs 38 and bars 37 are connected to the frame section 11.

The legs 38, which consist each of a U-shaped piece, are provided with blocks 39, as shown in Figure l.

The bars 40 are at one end pivotally connected to the section 11, as at 43, as shown especially in Figure 1, and at the other end pivotally secured to legs 41; the said legs 41 are pivotally secured to the frame section 10.

The bars 40 and the section 10 actuate a sofa frame member 42 by means of brackets 44 and 45, which are rigidly secured to said member 42 at one end and pivotally attached to the frame of the section 10; bars 45 are pivotally secured to the bars 40 and are pivotally attached to the brackets 44.

Legs 41 are pivotally connected to the end member by means of brackets. The member 46 also acts as a stop for the cushion (not shown).

Cables and helicals, indicated at 56 and 57, respectively, are arranged in the conventional manner.

An extension, or stop member, not to be extended any further than as shown in Figure 1, comprises bars 49 pivotally connected at one end to the frame section 10.

The said extension comprises a member 50 and bars 49 rigidly attached to the latter; the bars 49 are pivotally secured to the frame member 10 at their other ends, and said bars 49 are also pivotally connected by bars 48 to the legs 41.

I claim:

The combination of a sofa frame and a bed frame with a locking device, said locking device comprising two members provided with a notch and a stud, respectively for mutual engagement, one of said members being attached at the front of said sofa frame, the other member being secured at two points of a section of the bed frame, one of said points forming a pivotal engagement, the other point of attachment consisting of a slot, whereby to facilitate the locking and unlocking arrangement, a third member, the latter being pivotally connected to said section of the bed frame near the slotted end of said other member, and means to operate said third member whereby said third member is engageable with said other member to regulate the locking and unlocking of said members.
